OS dependent software ==> RAC目前使用 192.168.100.3  这个public ip 作为 interconnect private network ，且这个network是 OS自行找出的

即 RAC private network 没有使用 pjdb1_priv(1.1.1.0)的网段，

1.1.1.1    pjdb1_priv1
1.1.2.1    pjdb1_priv2
1.1.3.1    pjdb1_priv3

这里三个private ip 位于三个网段中，同样不建议这样做

可能是Clusterware安装过程中配置存在问题导致了 CRS使用 public ip作为 interconnect

建议

FOLLOW  <为Oracle Clusterware修改公用及私有网络接口>  http://www.oracledatabase12g.com ... 8E%A5%E5%8F%A3.html

重新配置 private network

Verifying the Interconnect Settings for Oracle Real Application Clusters

The interconnect and internode communication protocols can affect Cache Fusion performance. In addition, the interconnect bandwidth, its latency, and the efficiency of the IPC protocol determine the speed with which Cache Fusion processes block transfers.

To verify the interconnect settings, query the V$CLUSTER_INTERCONNECTS and the V$CONFIGURED_INTERCONNECTS. For example:

Example 12-1 Verify Interconnect Settings with V$CLUSTER_INTERCONNECTS

SQL> SELECT * FROM V$CLUSTER_INTERCONNECTS;

NAME       IP_ADDRESS IS_ SOURCE
--------------- ---------------- --- -------------------------------
eth2       10.137.20.181  NO  Oracle Cluster Repository

Example 12-2 Verify Interconnect Settings with V$CONFIGURED_INTERCONNECTS

SQL> SELECT * FROM V$CONFIGURED_INTERCONNECTS;

NAME       IP_ADDRESS IS_  SOURCE
--------------- ---------------- ---  -------------------------------
eth2       10.137.20.181  NO Oracle Cluster Repository
eth0       10.137.8.225 YES  Oracle Cluster Repository

SQL> DESC V$CONFIGURED_INTERCONNECTS
Name                   Null? Type
----------------------------------------- -------- ----------------------------
NAME                         VARCHAR2(15)
IP_ADDRESS                      VARCHAR2(16)
IS_PUBLIC                      VARCHAR2(3)
SOURCE                         VARCHAR2(31)

V$CLUSTER_INTERCONNECTS

V$CLUSTER_INTERCONNECTS displays one or more interconnects that are being used for cluster communication.
Column Datatype Description
NAME VARCHAR2(15) Name of the interconnect (such as eth0)
IP_ADDRESS VARCHAR2(16) IP address of the interconnect
IS_PUBLIC VARCHAR2(4) If the value is YES, the interface is known to the public.

If the value is NO, the interface is known to be private. Note that if the CLUSTER_INTERCONNETS initialization parameter is also specified, then it is expected that the interconnect is private. Oracle expects cluster traffic to be run on private interconnects only.

f the value is empty, it is unknown whether the interface is public or private.

Oracle Corporation recommends that you set the interface for Real Application Clusters (RAC) communication in the Oracle Cluster Repository (OCR).
SOURCE VARCHAR2(31) Indicates where this interface was picked up from:

Oracle Cluster Repository - Interface was configured in the OCR and Oracle Database found the interface in the OCR

Operating-system dependent software - Oracle Database automatically detects this

CLUSTER_INTERCONNECTS parameter - This initialization parameter was set

但是为什么olsnodes 与ocrdump里面看到的privatenames都是pjdb1_priv1、pjdb2_priv1呢？

我想起来，这套RAC曾经因为存储多路径的问题重建过OCR，可能在重建ocr时，未做网络接口配置，直接手工执行了VIPCA导致。oifcfg getif没有任何输出
